不对称改性镍催化剂（MNi）是制备光学活性化合物最简单的催化剂。 MNi可以通过将活性镍粉浸泡在光学活性化合物的水溶液中来容易地制备。 MNi 的独特功能是与大分子尺寸的活化金属表面和以分散单分子形式植入金属表面的光学活性化合物之间的合作相关的功能。金属表面充当用于氢化的活性氢发生器，而光学活性化合物充当反应物分子的立体化学调节剂。在这方面，对MNi催化剂的研究不仅有助于开发用于合成光学活性化合物的重要催化剂，而且有助于理解镍催化剂表面发生的各种特征现象。
The asymmetrically modified nickel catalyst (MNi) is the simplest catalyst for the preparation of optically active compounds. MNi can be prepared easily by soaking activated nickel powder in an aqueous solution of an optically active compound. The unique functions of MNi are those associated with cooperation between an activated metal surface of macromolecular dimensions and the optically active compound implanted on the metal surface in a dispersed mono- molecular form. The metal surface functions as a generator of activated hydrogen for hydrogenation while the optically active compound acts as a stereochemical regulator of the reactant molecule. In this respect, studies on MNi catalysts have contributed not only to the development of a significant catalyst for the syntheses of optically active compounds, but also to an understanding of various characteristic phenomena taking place on the surface of nickel catalysts.
